Ultra-low sulfur XRF spectrometer DUBHE-1610 - MWD XRF Series

In recent years, with the rapid increase of car ownership, automobile exhaust emissions have become one of the causes of environmental pollution, All countries have strengthened restrictions on the sulfur content of pollutants in vehicle fuel, At present, the most strict limit standard for gasoline and diesel is 10mg / kg, Monochromatic wavelength dispersive X-ray fluorescence spectrometry is one of the methods that can meet the requirements of ultra-low sulfur content in vehicle fuel.

Monochromatic wavelength dispersive X-ray fluorescence spectrometer model: DUBHE-1610, It has the characteristics of high sensitivity, simple sample preparation, low consumption and so on, which can meet the analysis of sulfur content in Gasoline, Diesel fuel, Jet fuel, Kerosine, Biodiesel and Gasoline-Ethanol Blends in petrochemical industry.

At the same time, DUBHE-1610 can also analyze the content of sulfur in solid and liquid, The detection limit of sulfur in water and other chemical products is up to sub ppm level.

See the following table for the LOD and analysis range compare of XRF instruments:

Standard No	Standard for sulfur detection method	Content range
GBT 11140-2008 ASTM D2622-2007	Wavelength dispersive X-ray fluorescence spectrometry	3mg/kg-4.6%，PLOQ-3mg/kg
GBT 17040-2008 ASTM D4294-2003	Energy dispersive X-ray fluorescence spectrometry	150mg/kg-5%，PLOQ-150mg/kg
NB/SH/T0842-2017 ASTM D7039-2015a	Monochromatic wavelength dispersive X-ray fluorescence spectrometry	3.2mg/kg-2822mg/kg，PLOQ-3.2mg/kg

High sensitivity and accuracy
• Johansson type Double Curved Crystals

> Efficient stimulation
By means of Johansson type double curved crystal, the high-strength characteristic lines of the target emitted from the light tube are diffracted and focused on the smaller surface of the sample, which greatly reduces the background of scattered rays and improves the excitation efficiency of elements in the sample.

> Accurate determination
Through the secondary diffraction and focusing of the element rays in the sample by Johansson type curved crystals, the excellent peak to back ratio of the element to be measured is obtained

• Design of digital optical path
Integrated digital optical path forming design, high precision to ensure the accuracy of spectral lines

High reliability
There is no moving part in the whole optical path. After factory tuning, the optical path will no longer produce errors and offsets, ensuring long-term use stability.

Wide adaptability
It is suitable for the detection of chlorine in refined gasoline, diesel oil (as low as ~ 0.5ppm) and crude oil.
